High-Pass Filter（RSL-H1300SA）

Product Introduction:

The RSL-H1300SA RF high-pass filter is designed to provide low-loss signal transmission across a wide 1300–2300 MHz passband. It features insertion loss of ≤1.0 dB, VSWR of ≤1.8, and a standard 50-ohm input/output impedance, supporting efficient integration into common RF systems. With attenuation of at least 20 dB from 650 to 1150 MHz, the filter effectively suppresses unwanted lower-frequency signals and helps improve RF front-end selectivity. Its compact 20 × 7.9 × 3.8 mm package and wide −40°C to +70°C operating temperature range make it suitable for space-constrained equipment and reliable operation in demanding industrial environments.

Typical applications for the RSL-H1300SA include L-band and S-band communication systems, RF transceivers, wireless infrastructure, telemetry equipment, microwave links, radar subsystems, satellite communication terminals, spectrum monitoring devices, test and measurement instruments, and custom RF front-end modules. The broad 1300–2300 MHz operating range and low insertion loss help preserve signal strength, while the lower stopband rejection reduces interference before signals reach amplifiers, mixers, or receivers. This compact 1300 MHz high-pass filter is well suited for OEM integration and B2B projects requiring wideband performance, effective low-frequency suppression, and stable operation.
